Knotel is crying foul at WeWork’s alleged attempts to steal customers and intel.

Co-working company Knotel claims rival WeWork sent two spies to seven of its locations in Manhattan in a “systematic attempt to pilfer Knotel’s proprietary information and trade secrets,” according to a cease and desist letter sent to WeWork and obtained by the New York Post.

The two WeWork employees used fake names and posed as founders of a start-up looking for new space for their six-person company, according to the letter.

“The snoops were so amateurish and unethical that the project feels more like an improvised Keystone [Cops] spying operation than something dreamed up by [Neumann],” Sarva said. “At least, I give him the benefit of a doubt.”

WeWork has more than 200 locations across 52 cities, with 44 of its offices in New York City. Knotel only has 24 location, all but one of which is in the city.
